Mechanical stiffness orchestrates distinct regulation of MRTFs and YAP/TAZ transcriptional cofactors in hepatocytes

The FEBS Journal, EarlyView.
MRTFs and YAP/TAZ proteins, or mechanosensitive transcriptional cofactors (MRTcoF), regulate common genes associated with cellular contractility and immune cell infiltration. Their differential regulation in response to stiffness is linked to changes in hepatocyte's aspect ratio. MRTFB does not undergo nuclear translocation under these conditions. This
